5, compact overall structure, light weight, a people can operate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is schematic diagram of the present utility model;
Fig. 3 is the structure chart of hand-held rod member.
In figure: 1 hand-held rod member, 11 first cavitys, 12 second cavitys, 2 stationary knifes, 21 straight sections, 22 segmental arcs, 23 screws, 24 rubber softs, 3 direct current generators, 31 output shafts, 32 worm tooth shapes, 33 bearings, 4 worm gears, 41 worm-wheel shafts, 5 moving knife, 6 switches, 7 battery components, 8 controllers.
Embodiment
As shown in Figure 1 to Figure 3,
Prune an electric pruning shear for high-altitude branch, comprise hand-held rod member, Worm Wheel System assembly, direct current generator, stationary knife, moving knife, controller and battery component, be described in detail respectively below.
Hand-held rod member 1, hand-held rod member adopts aluminium alloy pipe to make, and comprises three sections of upper, middle and lowers, as Fig. 3, and adjustable length, hand-held rod member, by flexible mode adjustable length, adapts to the application of different occasions.For example for tall trees branch, can extend, for relatively short branch, can shorten.
On the top of hand-held rod member 1, be provided with the first cavity 11 and the second cavity 12 that Worm Wheel System assembly and direct current generator are installed respectively, wherein carrier-the housing of two cavitys and hand-held rod member one, also can be fixed together by securing member.
Then at the top of the first cavity 11 housings, a stationary knife 2 is installed.And stationary knife 2 entirety become hook-shaped, and wherein the blade of stationary knife comprises the straight section 21 in outside and the segmental arc 22 of inner side.For ease of reconditioning stationary knife, stationary knife is fixed installation by screw 23, and is provided with a rubber soft 24 at the point of a knife place of stationary knife, prevents that stationary knife point of a knife from hurting sb.'s feelings.
What direct current generator 3 was vertical is arranged in the second cavity, and output shaft 31 upward.
Direct current generator 3, on the basis of common DC motor, produces one section of worm tooth shape 32 on output shaft 31, form worm structure, and the output shaft of direct current generator is also the worm screw in worm and gear assembly, is one.And bearings 33 is carried out in output shaft two ends, improve the intensity while rotating.
32 sections of worm tooth shapes on output shaft coordinate with worm gear 4, and above-mentioned worm gear 4 two ends are rotating being arranged in the first cavity 11 directly; And on worm-wheel shaft, fix a moving knife 5 rotating in the lump along with worm-wheel shaft 41, during cooperation, a square hole is set on moving knife, then coordinate with the square shaft part on worm-wheel shaft, wherein moving knife 5 is positioned at the downside of stationary knife 2, by control system make and moving knife rotation process in complete snap-action with stationary knife;
The switch 6 of controlling direct current generator work is arranged on the hypomere of hand-held rod member, is convenient to hand-held.
Battery component 7 provides electric energy to direct current generator, and controller 8 is for controlling the start-stop action of moving knife; Battery component 7 is the lead accumulators that are fixed on an accessory cart, is so conveniently moved, and is electrically connected between battery component 7 and motor.So just can effectively alleviate the weight of hand-held rod member, battery component is also convenient to be moved simultaneously.
During use, first a people holds hand-held rod member can be to branch pruning,, regulate suitable length, then stationary knife is extended to branch place to be pruned, then hook branch, because stationary knife is hook-shaped, can not come off, alleviate operating personnel's labour intensity simultaneously, then press switch, machine operation, stationary knife slowly rotates, in rotation process, complete pruning with stationary knife interlock, last moving knife rotates one week, stops, and completes once and prunes.Sort circuit control is easy to realize, and between described stationary knife and hand-held rod member, limit switch is being set, and described stationary knife is rotated and within one week, complete a pruning action.
Certainly, by limit switch being set between described stationary knife and hand-held rod member, making described stationary knife rotate 180 and spent the rear auto-returned of a pruning action home position, the action of simulation scissors is also fine.
Certainly, for attractive in appearance, also battery component can be selected to lithium battery, be convenient to like this be fixed in hand-held rod member, volume is little, elegant in appearance, and cost is higher comparatively speaking.
Jagged blade can also be set certainly on stationary knife and moving knife, as required configuration.
Except the technical characterictic described in specification, be the known technology of those skilled in the art.
